EXPERIMENTAL INVESTIGATION OF THE OIL RECOVERY POTENTIALS OF ALTERNATIVE ASP FORMULATIONS FOR SANDSTONE AND CARBONATE RESERVOIRS

Despite the promising nature of alkali-surfactant-polymer (ASP) flooding, its application is limited by various technical issues and environmental concerns. The goal of mitigating the impact of these limitations has led to research into the oil recovery potential of alternative chemical agents. Nevertheless, there is limited deployment of these alternative chemical agents in field application due to high chemical cost. Therefore, this study focuses on investigating the potential of alternative ASP formulations composed of monoethanolamine (ETA), sodium cocoyl alaninate (SCA) / hexadecyl-3-methyl imidazolium bromide (C16mimBr) and Schizophyllan (SPG) for their enhanced oil recovery application in sandstone and carbonate reservoirs, respectively. Conventional ASP formulations are deployed for comparative purposes. A comprehensive approach has been deployed to study the EOR potential of the proposed formulations.
